Can Subscriptionpublish MQTT to AWS IoT?

I would like to publish MQTT notifications from Orion's Subscription to AWS IoT topics.
I am aware that Orion can do MQTT notifications, but I would like to know if it is possible for AWS IoT and what authentication is supported in that case. (certificate? user/pass?)
